 Abstract
This paper shows the particularities of developing a risk analysis in order to determine the safety distances between the national gas transmission pipelines system and the social and industrial objectives located in their neighborhood. Based on the event tree analysis on pipeline commissioning, on the causes and probability of occurrence of such events we chose to analyze the worst case scenario from the perspective of human health and safety, of the security of constructions, equipment and environment in the vicinity of the pipeline and, taking this worst case scenario into account, we drafted a procedure for the determination of the safety distances. The paper also shows the main physical and procedural means and methods to remedy and settle the risk entailed by the operation of the gas transmission pipelines for the purpose of providing some rationally sized safety areas.

 Rezumat
În lucrare se prezintă particularitatile realizarii analizelor de risc în vederea stabilirii distanţelor de siguranţă dintre conductele apartinând sistemului national de transport al gazelor naturale şi obiectivele sociale şi industriale situate în vecinătatea acestora. Pe baza analizei arborelui de evenimente privind cedarea în exploatare a conductelor, a cauzelor şi probabilităţii de producere a unor astfel de evenimente, s-a selectat scenariul de cedare care poate avea consecinţele cele mai grave pentru sănătatea şi viaţa oamenilor, pentru securitatea construcţiilor, echipamentelor şi mediului din vecinatatea conductelor şi, tinând seama de acest scenariu, s-a elaborat o procedură de determinare a distanţelor de siguranţă. Sunt prezentate, de asemenea, principalele metode şi mijloace, de natur fizica si procedurala, de tratare si diminuare a riscului atasat functionarii conductelor destinate transportului gazelor naturale, în scopul prescrierii unor distanţe de siguranţă de mărime raţională.
